How to calculate an arch radius!

[giantgrowth]

Yes sir I used to build arches on porches, screened in porches. We used a string. Tied to a pencil. Same formula. An older Mexican man named Lupe ramirez taught me that when I was 18 years old. He showed me many things in construction. Thank you

How you displayed the calculator and explained this was excellent, subscribed! Thanks

And this is where my math left the room.

Please make more video like this. Like how to calculate the ridge? Etc. great work!!!

The calculator solved for R = H/2 + (W^2)/8H in case anyone was wondering.

Where:
H = 26.5”
W = 105.5”

I like these little videos teaching people new things they may have not known. Thanks.

I know three ways to do that and none of them use math, so I'm kinda glad for the guy who gave the formula above.

Good shit bro. Sparky here. I enjoy your videos.

[jasonperez]

And just like that I learned something. Awesome. Tips have been great from your recent posts

Glad to see the fireplace is installed. We often have to wait.

I did a lobby once where it was 4 radius’ meeting and like swirling together between 4 different tiles and the prints were totally unclear and I had to basically make it from scratch. That app was a game changer that day. Otherwise I dont find myself using it much in the tile world.

I was taught with a string and pencil looks like this is a good way as well subscribe love watching new tricks

I do arches with out math really thee is a simple way to do it with out a calculator or math And I build solid one pour Concreted staircases with concaved edges with out a calculator .... but a good video for the people that need to use Calculators and can not function with out Tech

I haven’t layed out any arches in a minute. We were doing radial arches on this one health first building, all suspended. That was a fun one . Metal studs of course .

How does that wrk when your run is over 8 ft 9-1/2 inch but the ply wood is only 8ft?? Pls explain. Or Did you start with wider ply wood and cut it to 8ft -9-1/2 inch then you pulled off ea corner of plywood to get nail point for arch ? That all makes sense in my head as long as the plywood I see there isn’t just 8ft it had to be 8 ft 9-1/2 inch right???? Wish I was smarter but that’s why I’m commenting to hopefully add some knowledge to the bank!

[zanesmith]

Is that piece of plywood 8’-9 1/2” long? That was the run, so I assume you had 10’ sheets that you cut down to fit the run? (I’m assuming hallway?)

Nice done! Thank for math and Google!
